Hello from Australia where no one does hondas ;(

I have done a lot of research etc yet i have not yielded all the answers that i want. I have an em1 civic (99 si) and i have a b18cr motor. I want to make it an all motor beast. I have access and will use 100ron gas as well as i/h/e etc. My question, is what intake manifold should i use to make the most all motor power. I dont care about the power before vtec engagement so i am looking for vtec on up power. I know some will say keep the oem itr im but i know there is extra power to be made with others but there is not many (if any) dynos for aftermarket im on a b18cr that is all motor or with just bolt ons. I have a fujisubo cat back rm01a, a samco intake with the bmi 3inch filter and velocity stack, will be buying a header (either toda or hytech), bought 4.92 final drive, hondata s300 v3, and now the im. I was thinking either a victor x , performer x, or skunk2 ultra with a 65mm throttle body. If any of you can help me based on facts and dyno graphs i would greatly appreciate it. I will also be adding some cams (not sure which ones yet) and cam ideas to match my setup would be great.
